How we approach skylight replacement in Coalisland
For Coalisland homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. Typical uses for skylight replacement include yellowed domes, misted glass and leaking roof windows.
From Coalisland to Dungannon, Cookstown and Portadown, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Upstand rebuild and insulation
- Dome to flat glass upgrade
- Roof window replacement in pitched roofs
- Fixed to electric opening
- Misted glass unit replacement only
- Cures most chronic leaks
- Often reuses the existing opening
Before you order: points to check
- Old glass and domes are disposed of responsibly
- Enlarging the opening changes the structure and may need approval
Do you need permission in Coalisland?
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage. A side-facing window within 15 m of a neighbouring boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Technical Booklet F1 (2022) asks for replacement windows and rooflights in existing homes to reach WER Band C or a U-value of 1.6 W/m²K, assessed in the vertical position. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight replacement in Coalisland
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
Will I need planning permission in Coalisland?
In Northern Ireland, roof alterations come under Class B of the 2015 order: a rooflight facing a road must not project more than 15 cm and must sit at least 0.5 m from the ridge, eaves, verge and party wall.
Do I need to be at home for the survey in Coalisland?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
